Systemic circulating inflammatory burden and periodontitis in adolescents.

Area of Science:

• Oral Health Research
• Cardiovascular Disease Epidemiology
• Adolescent Health

Background:

• Periodontitis and cardiovascular disease (CVD) share common risk factors, including inflammation.
• The early establishment of this association in adolescents is not well understood.

Purpose of the Study:

• To investigate the association between systemic inflammatory burden related to CVD risk and periodontitis in adolescents.
• To explore mediating pathways involving socioeconomic status, adiposity, smoking, and blood pressure.

Main Methods:

• A population-based study of 405 Brazilian adolescents (17-18 years old) was conducted.
• Structural equation modeling was used to analyze direct and mediation pathways.
• Systemic inflammatory markers (IL-1β, IL-6, IL-8, TNF-α) and periodontitis indicators (BoP, PD, CAL) were assessed.

Main Results:

• Higher systemic inflammatory burden was directly associated with increased initial periodontitis.
• Lower socioeconomic status and smoking mediated initial periodontitis through systemic inflammation.
• A dose-response relationship was observed between systemic inflammation and moderate periodontitis.

Conclusions:

• Systemic inflammation is an underlying mechanism for early periodontal breakdown in adolescents.
• Social vulnerability and smoking are significant triggers for this process.
• Findings suggest the periodontitis-CVD association begins in adolescence, emphasizing preventive strategies.
